The sides 3 3 of the window-frame are-see ourely joined to the sill 2 by the rivet-s 1, the part. 3 also serving asla 1o closure for t 0 end .2 of the sill 2.

Referring now more particularly to Figs. 2,

I 3, 4, and 5, it will be seen thetop4 of the easing 1 comprises substantially the L-shaped faee-stri S 46 4", the under connecting-strip 4, whic 1 issecurely interlocked with the face-plates 4 4 and the upper. connecting strip 4?, also securely interlocked with the.

The outer face-strip 441s formed with an zo'indentation to produce a groove 1 for preventin the rain from coming into contact with the upperpart of the window-frame.

' The top 4 is secured to. the sides 3 by hav: ing. the face-strips 4 4 riveted to the parts 3 3 on the side of the casing and by having" 5 the rib 7 secured to 'the part 3?, as before explained.

The windowl'O comprises the frame 1 1 and the glass pane G, and the frame .11 consists of a top 12-, the sides 13 13, the bottom 14, and

- the central nie1nber15, all of which areconstructed of sheet metal in the manner now tobe explained. I,

The bottom 14 of the window-frame 11 is constructed of a single piece of metal bentv in a substantially nfshapeto form the front and back faces 14*. 14" andithe top faces 14" is, the top faces being forn'ied with an intermediate indentation or groove 14" to receive the window-glass G, as shown. The outer 6o face 1 1 is in a lower horizontal lanethan that containing the face .14, so 1. lat should -'f01' any reason water gather in the groove 14" it will ilow over the outside instead of the in-v side. lhe bottom edges 01'' the faces 14 14" are formed with hinged port-ions 1 4, through ocket 3*, runmngits which and the hinged portions 17 of the weather-stripl7 the hinged rods 18 pass. These sealing or weather strips 17 are best shown in Figs. 2, 3, and 7,. by reference to which it will be seen the said strips run the entire width of the niii leiv-i'rame and have.

their edges 17" 'bent to engage the sill and their adjacent edges 17 formed into hinged portions 17', through which a hinged rod 17 passes!v T he; strips 17 are cut away at intervals, as at 17 to receive the rollers 19, mounted on the rod 17 for riding the. ridge 2" of the sill 2'- whe1rthe window is closed to tightly hold the'edges 17" in engagement. with the sill, as best shown in Fig. 2.

Midway the ends of the bottom 1 place a socket 20, in which is held for vertical move- .ment a short red-section 21, having a fingerpiece 2-2, and the said rod 1s adapted to pas:

down into the socket 5 of the sill and is held in such'position by the coil-spring 20, a: shown. The socket 20 has a slot 20" throughwhieh and a slot 14- in the face 14.

the finger-piece 22 passes. The red .21 .iormthe len er pivot or fulcrum for the window 11 the sill. The socket 20 may be of any'ap provedconstruction but 1 preferably 1' orm it as shown, with the. main tubular body 20",

l 1oriZo1:.tal wing 20 for engaging the top fact wirgs 20- 20, the said body '21) having an e1 larged bore .20 to receive the rod 21 and th spring 20, which 8])111. g and red are held 5 t ieir proper correlative positions in tl socket by the bushing 20*, as shown in Fig.

i The sides 13 are preferably constructed shown in Figs. 1 and 4, by reference to Wlllt it will be seen each side l3'conn'irises two se tions 13 13 interlocked in such a inann as to form arib 13, running the entire long of the side fronrtop to bottom, which str 13 enters into and cooperates with the groo 39 in the easing-frame when the window closed to form a seal between the casing a. window-frame. The sections 1.3 13 also locked together by the] 'i-shaped str. 13, and at this joint the sections 13 13" so formed as to produce a groove 13, which the window-glass rests. The sides are secured to the bottom 14 by rivets 13 in any other equivalent manner.

The top 12 01" the windowframe eompri a pair of substantially -shaped strips 12 of precisely the same construction, 2 the top closure consists of a plate 12", W1: has integral ribs 12" 12" and whose edges 12 interlock with the edges 12 12 of strips 12 12 to hold said strips in proper sition. The-strips 12 12 are securely 'tened' at their ends to. the ends of, the side by rivets oiotherwise and as clearly sin in Fig. .1, and the. said strips have their e1 12 12 separated to allow ior the insertio the window-glass G before the top plate has been put into place.

, otherwise be possible.

window-frame side parts, showing a modifiedway of joining the parts 3" and-3 to the part 3.

By constructing the window, casing and frame entirely of metal-I provide an absolutely fireproof structure, as there is absolutely no inflammable material present: By constructing the various parts of sheet metal rather than of solid casting I amen abled to more cheaply and durably construct the window frame and easing thanwould:

Should for any reason it bedesired to remove the window-frame from its casing for reglazing' or otherwise, it is only necessary to witl drawithe rods into the respective-sockets and-outijifengagement with the soeket inthetop of the window-casing and'intdthesill, whenthe windowinay 1 ing and in which the partsaresccurely inter- 3 5 be readilyrer'noved.
